A Video subgroup plenary was held 11:00-13:00 on Wednesday. Reports of BoGs were given as follows:
MPEG-7 Visual:
FDIS of new edition
Document on using descriptors for scene classification
CDVS:
New part 14 for SW/Conf/TM
Awareness event planned for Warsaw
Software newly structured, outputs information about matching process, acceleration of feature point detection, Matlab interface, all uses BSD header
Implementation on mobile device demonstrated, coding/decoding requires unexpectedly long time (to be further investigated), matching is acceptable
FDIS preparation: One comment points out that resampling is not sufficiently specified (could have consequences on conformance?)
DoC to be presented Friday
IVC:
Reviewed all input documents
Visual testing planned for Thursday, 9 volunteers needed
For LD, all bit rates are in the margin of +/- 3%. For RA
This seems to allow making an assessment (qualitatively) whether within the last 9 month IVC has reached a level of visual quality that would be comparable to the other codecs
Considered for new ITM: Lagrangian optimization (non-normative); stronger deblocking filter covered by expired patent of 1993; improvement of transform, add 4x4 transform for intra for which a patent has been applied for by proponents.
Improvement of WD text,
RVC:
Review of PDAM Thu 11:00 (Stuttgart)
White paper draft has been delivered
CICP:
Alexis Tourapis and Teruhiko Suzuki took responsibility for preparing 23001-8/DAM2 which was later presented during the Thursday plenary.
VCB:
DoC on software and conformance prepared.
Note: Since the AVC conformance was used as a kind of starting point for this, the same problems pointed out by US may apply to Amd.6 of Conformance. In Amd.44, it is planned to resolve them for the case
